Do you think Heavier product will drop more faster than lighter product? Humans believed for over two thousand years Aristotle law that shows heavier product is falling faster then lighter product. But Galileo Galilee thought different way and he dropped one big cannonball and one small bullet fall 100 meters and this explain that even the weight very different, they were falling in the same speed. This experiment happened on 1590.
As the acceleration continues and the object’s speed increases, the air resistance force rises. During this time the net acceleration force, which is the difference between weight and air resistance, slowly decrease so that the acceleration becomes less and less. Finally when the air resistance becomes equals to the weight of the object and it continues to fall at the same speed with no acceleration.
A free falling object is an object, which is falling under the sol influence of gravity. A free falling object has an acceleration of 9.8 m/s/s, downward on Earth. This numerical value for the acceleration of a free falling object is such as important value that it is given a special name. This is known as the Acceleration of Gravity. It is such an important quantity that physicists have a special symbol to denote it,g. There are slight changes in this numerical value to the second decimal place, which are dependent basically upon on altitude
Maximum speed for different objects will vary a lot, depending on the mass, size and shape of the falling object. Without a parachute a falling person would reach a speed of around 180k/h but with a parachute only about 15. For a feather the acceleration phase is hardly noticeable and it is almost immediately falling at its terminal speed.
Air resistance is a friction force and the energy taken out of a falling object will become heat energy in the air immediately around the object. Some of this heat will cause a rise in temperature of the object itself. It is for this reason that the outer layers of meteorites are usually molten by the time they reach the earth's surface and the heating of re-entering satellites is a significant design factor.
Free fall is a special type of motion in which the only force acting upon an object is gravity. Objects undergoing free fall, are not run into a important force of air resistance and they are falling under the sol influence of gravity. Under such conditions, al object will fall with the same rate of acceleration,indifferent of their mass, because consider the free falling motion of a l000 kg baby elephant and a 1 kg overgrown mouse.
How does air resistance affect a falling object?
Resistance force slows the object down and increases the falling time of the object. A falling object accelerates downwards due to gravity, when the air resistance is equal to the force of the gravity then the falling object reaches terminal velocity where there is 0 acceleration.
